Bennett, 34, will depart Montgomery Waters Meadow at the end of his contract next month after two seasons at his home town county club.
The former Blackburn, Norwich and Brighton man was a favourite among team-mates and supporters. Telford-born Bennett played 83 games in all competitions for Town and scored three goals. He was a versatile option for Steve Cotterill and a well-respected experienced professional behind the scenes.
"Truly honoured to have had the opportunity to represent my home county club over the last two years," Bennett wrote on Instagram.
"Playing in front of my kids has been a massive highlight and one I will cherish.
"I've met some incredible people and loved being a part of the club from the moment I signed.
"Thank you to all the players, staff, and fans that have supported me during my time. Who knows what the future holds but for now...thank you."
